Reinforced fiberboard pallet

Claim 2

A portable materials handling accessory adapted for use in lift truck operations consisting essentially of a single fiberboard sheet having a central panel forming an elevated platform and having side portions, integral with said central panel, folded under said central panel to provide two hollow sleeves extending beneath and on opposite sides of said platform and defining a passageway for a lift truck fork entry beneath said platform, bridge structure means including a bridge board, longitudinal openings in said two hollow sleeves adapted to receive said bridge board, said bridge board supporting one end of said platform, and provided with two footings, one attached to each end of said bridge board and located respectively, one in each sleeve to place said platform in stress, and a second bridge structure means including a bridge board, second longitudinal openings in said two hollow sleeves adapted to receive said second bridge board, said second bridge board supporting the opposite end of said platform, said second bridge board having two footings, one attached to each end thereof, and located, respectively, one in each sleeve to place said platform in suspension and under stress.

Claim 3

A portable materials handling accessory as claimed in claim 1 wherein two "V" shaped stringers located, respectively, one in each hollow sleeve, support the opposite sides of said platform.

Claim 4

A portable materials handling accessory adapted for use in lift truck operations comprising a sheet of fiberboard, having a central panel adapted to form an elevated platform and a plurality of longitudinally spaced side portions integral with said central panel extending laterally from both sides of said central panel, each of said side portions having a series of laterally spaced scores to divide said side portions into a side panel, a bottom face panel, an inner upright portion and an under panel, two opposite and parallel end cuts along the boundary between said inner upright portion and under panel to provide two longitudinal openings, whereby said side portions may be folded along said scores under said central panel with surfaces of said inner upright portions in face to face relation and with said longitudinal openings in face to face relation to provide two hollow longitudinally spaced sleeves extending longitudinally beneath said central panel, with oppositely located spaced apart longitudinal openings in the opposite end portions of each sleeve, and means fastening each under panel to the underside of said platform to reinforce said platform, two bridge structures each comprising a bridge board, two footings, one for each end of said bridge board, means fastening said two footings to said bridge board, each of said two bridge structures being placed beneath opposite ends of said platform, with each bridge board located in one of said two longitudinal openings in face to face relation and with the footings on opposite ends of the bridge board located in one of the two hollow longitudinally spaced sleeves, respectively, said bridge board supporting said platform and said footings abutting, respectively, the side panel in each sleeve to stress said platform and hold said platform in suspension.

Claim 5

A portable materials handling accessory adapted for use in lift truck operations comprising a sheet of fiberboard, having a central panel adapted to form an elevated platform and a plurality of longitudinally spaced side portions integral with said central panel extending laterally from both sides of said central panel, each of said side portions having a series of laterally spaced scores to divide said side portions into a side panel, a bottom face panel, an inner upright portion and an under panel, two opposite and parallel end cuts along the boundary between said inner upright portion and under panel to provide two longitudinal openings, whereby said side portions may be folded along said scores under said central panel with surfaces of said inner upright portions in face to face relation and with said longitudinal openings in face to face relation to provide two hollow longitudinally spaced sleeves extending longitudinally beneath said central panel, with oppositely located spaced apart longitudinal openings in the opposite end portions of each sleeve, and means fastening each under panel to the underside of said platform to reinforce said platform, two bridge structures each comprising a bridge board, two footings, one for each end of said bridge board, means fastening said two footings to said bridge board, each of said two bridge structures being placed beneath opposite ends of said platform, with each bridge board located in one of said two longitudinal openings in face to face relation and with the footings on opposite ends of the bridge board located in one of the two hollow longitudinally spaced sleeves, respectively, said bridge board supporting said platform and said footings abutting, respectively, the side panel in each sleeve to stress said platform and hold said platform in suspension.

Claim 6

A portable materials handling accessory as claimed in claim 3 wherein said two footings comprise geometrically square configurations having opposite edges aligned along the longitudinal axis of said bridge board, opposite edges abutting said side panel and inner upright of said hollow longitudinally spaced sleeves, respectively, to prevent said platform from tipping.
